轮毂电机技术在实际应用的过程中表现出了非常明显的优势,即占用资源较少、整车结构简洁、可利用空间较大、应对故障能力较强、车辆操控性能好等,并且通过对此技术的应用,还有效的实现了电子差速的有效控制。在20世纪70年代,保时捷公司研发出了将轮毂电机安装在前车车轮的电动汽车,并且还在矿山类型的运输车辆领域得到了非常广泛的应用。对于轮毂电机技术的研发,时间最长的国家仍属于日系厂商。如丰田、通用等国际汽车巨头也对轮毂技术有效全面的掌握和应用。就目前国内汽车而言,也对轮毂技术进行了有效的研发和利用。就以福特F-150型汽车而言,其正是因为采用此项技术,才将车内所有的传动部件全部替换,此种操作促使汽车车身结构得到了大大的简化。
